\ To all whom t may Concern: i

.. Beit knownthat we, Sir ARTHUR TREVOR y DAWSON, knight, and GEORGE THOMAS Boexi-IAM, both subjects ofthe Kingof Great i Britain, residing lat Vickers House, Broadway, Westminster, inthe county of London, England, have invented certain new and useful Improvements in or Relating to Gun Carriages, of which the following is a speciication; i l

\ x This invention relates to a cycle side car adapted to serve as a carriage for a breech loading gun of the Maxim or other type. i

According to this invention the parts of the side car are so constructed and arranged that f the gun and gunners seat occupy such aposition relative to each other, `that the gun can be operated under ordinary circunistances without its being necessary for the gunner to leave his seat. The seat is preferably `arranged contiguous to the side car axle and the training pivot of the gun is carried by a suitable framework (forming part l the gunner would have to leave his seat in order to operate the gun.

i `In order that the said invention may be Aclearly understood and readily carried into effect, we will describe the same more fully with reference to the accompanying drawings, in which:-`

Figures l, 2 and 3 arerespectively a front f elevationa side elevation and a plan showing a side car (attached to a motor cycle) constructed in accordance with our invention.

Fig. 4 is a side elevation of an ammunition `container carried by the side car and having `an improved device for retaining the ammu nition boxes in position, and Fig. 5 is a detail.

The gun shown in the drawings is of the Maxim type and its crosshead c is carried by an upper carriage c whose training pivot `is supported in a socket C. This socket forms the junction piece of two tubes C C GUN-CARRIAGE.

connected at their rear ends to the side car axle. The axle thus constitutes the base and the socket theapex yof a triangular Ystructure. Arranged across the said two tubes is a training arc CZ for the reception of a rearward extension of the upper carriage c to `which is connected the elevating gear preferably comprising a screw and hand wheel as shown. The upper carriage and the crosshead are normally connected to getlier but whenthe gun is to be used for high angle 'firing `these parts are disconf nected so that the; gun together with the cross head can be lswung horizontally through an angle of 180 degrees as above stated; the `elevating gear is disconnected from the gun before this operation is effects ed. When the gunis in this position the breech end can be depressed as shown by chain lines in Fig. 2 for high angle firing.

` The cartridge belt box C* may be carried by the mechanism casing ofthe gun as shown or by the framework of the side car and a detachable shield D moving with the position by a` strap Ex (Fig. 3) or by a transverse bar E (Fig. 4) carried by arms EL pivoted at e2 to ther-ear portion of the spring frame. The bai' is held in its operative position by a` spring controlled clip or catch E3 which can be displaced to enable the bar to be moved downward about its pivots and thereby liberate the boxes which can then be drawn rearwardly from the spring frame E. The latter also serves to carry the shields when they are detached, and carries two blocks (one of which is shown at E4 in Fig. 4) having suitable grooves for the reception of the legs of a detachable tripod mounting for the gun, which can be employed when the gun is removed from its mounting on the gun carriage. The spring supported frame for the ammunition carrier illustrated at Fig. 4 forms no part of the present invention. The

framework of the side. car may comprise in addition to the triangular structure above referred -to, a second or lower ktriangular structure F,vv F, Ff also `having the vaxleB as` its base. The first mentioned structurey is...V inclined forwardly and -upwardly while'the' lower structure is' inclined. downwardly7 "in, Figs.l 1 to 3 and forwardly and downwardly 1 in Fig. 4*; the apex-orzjgunetion piece F ofy the lower structure is connected to thesocket' C ofthe other `structure by a member F2.

The said junction piece F` may. act as a sup4 i portl for-theV gunnersseat or, as illustrated more particularly at Fig. 5v the `gunnersseat A may-be carri-ed on the member F2. It

will be observed'that the. seat A to which ythe kback restA` F4 is secured, isz'tself` c`onnected toi the-memberfFf by the seat'bracket i, F3 which flatter is secured to.- the. member F2 20* in any `suitable manner. v.'Ihetubes C. Cf
